  • Hi, I have a lambo gallardo and would like to enavle the navigation service. Can I follow the steps to enable it. If not, how can I do it? Thanks

    • In RNS-E navigation should work be enabled in device as it is. Just insert navigation map DVD to the drive behind the screen.

  • If a change the dvd boot and he ask for the code but the code is correct
    He d’ont start up can i change this in this menu ? Or is this an other problem ?

  • My dog managed to get car in this mode stepping on the buttons. How do I get it/exit?

    • turn the ignition off.
      how did you dog managed to step on vertical surface?!

  • My radio is intermittent and the Satellite only allows me to listen to the freeview channel (also intermittent).
    The radio will work fine then suddenly progressively lose all presets leaving just static, like the signal goes out. Sometimes if I slide the head unit out it all comes back again but I don’t think its a loose connection. Seems like it is but I’m not sure.
    I read that it might be the trunk lid mounted antenna amplifier so I ordered a new one – any thoughts ?

  • Hi, when i connect obd with my car ( i have audi a4 b7 ) and I want to enter on my navagation, i have an error and don’t let me access. You have an idea why I can’t access? Thanks

  • In a4 b7 navigation and parktronic controllers are in another network, you need to change 2 wires in obd connector. Check obd conector pinouts for b7.

  • My RNS E unit works perfectly apart from the screen opens and closes on unlocking the car. When I press the screen open display button to remove the DVD or SD card, it opens then immediately closes. Any ideas?
